Kulafarmer Report post Posted January 3, 2016 Curious what the lightest weight leathers are you have sewn with a Cobra class 4 or similar machine, and what needle size, thread etc. Need to sew piping and covers for chair cushions, 3.5-4 oz? Quote Share this post Link to post Share on other sites
pcox Report post Posted January 3, 2016 you need a lighter duty machine. You can do it with yours but it will need a lot of adjustments and a flat table adapter. Quote Share this post Link to post Share on other sites

Have a sailrite ultrafeed, was thinking i might use that, way easier on thin stuff, was just curious,,, Quote Share this post Link to post Share on other sites
Ferg Report post Posted January 3, 2016 Ninety five percent of the adjustment is needed in the top, I seldom change the bobbin tension. I believe almost every dealer represented on this forum will have a chart for needle and thread sizes, just ask. Personally, I don't see all that big a problem with stitching 3.5 to 4oz. IF you don't mind spending some time for the new adjustments. BTW: I have sewn all the things you wish to do on either the cylinder arm or flat bed. ferg Quote Share this post Link to post Share on other sites
